In Ultima Online, the Recipe Book is an item introduced to help players organize and store various crafting recipes they acquire. Similar in function to the Bulk Order Deed (BOD) books, the Recipe Book allows players to collect and categorize up to 250 different recipes in one place. This storage system aids in reducing clutter and helps players manage their crafting materials more efficiently. Additionally, the Recipe Book provides features for sorting recipes and can be used to sell them directly from the book, enhancing the trading and crafting experience in the game​
